Autolites last as long for me as the NGK's. Either of them last about 10k miles for me. Any longer than that and I start getting missfires. The Autolites can be found for about $1.00 each
I use Autolite plugs plat 1 cheepos that get me 400 miles per tank and seem to handle continuous high rpm output ( drove across the US in four days)
After changing the plugs from OEM's to Autolite 3923's, the coil packs started popping up. I've read that the Autolites are smaller than the OEM's, so they don't hold on as tight...and then somebody else said this is bogus and they're both the same. Whatever the reason, the coil packs on my car do not like the Autolites.
I bought some Autolite Platinums and now I find out they are crap Anyway, I needed something fast. Replaced them earlier this afternoon after work and so far so good. Acceleration is ALOT smoother.
Now I'm running autolites one range colder than stock at .028 and they run great...
i put in some 3922s and i can hear it misfire when its idling, but it seems fine when im giving it gas.
Just installed my autolites 3922 (one range colder than stock 3923) they were gapped to 0.025" with this gap I'm having some problems on hot startups, colds ones are ok. I'll regap them tomorrow and see if it gets better, maybe I'm having some loss in performace as well due the small gap....
don't feel like changing them every oil change like I did with the autolites that constantly misfired...
Last time I tried the 3922s and I was pleasently surprised with how smooth the car runs. I haven't had a misfire code since I changed over.
i'm running autolites right now and i'm not too impressed with them
